COOKING-RANGE.

SPECIFICATION forming part of Letters Patent No. 429,546, dated J une 3,1890. Application led August 3, 1889. Serial No. 319,624' (No model.)Patented in England November 29, 1887, No. 16,432.

To all whom it may concern.-

Be it known that I, THOMAS ROGERS, a subjectof the Queen of GreatBritain, residing at 27 The Triangle, Bournemouth, in the county ofHants, England, have invented new and useful Improvements inCooking-Ranges, (for which I have obtained a patent in Great Brit ain,No. 16,432, dated November 29, 1887,) of which the following is aspecification.

This invention has for its objects to provide an improved cooking-rangewherein the heat from the fire is utilized to the best advantage forheating the ovens and the boiler, to provide a novel construction ofparts whereby a range of va given size can be heated with acomparatively small quantity of fuel, and to provide novel means forheating the air that supports combustion and produce a range thatpractically consumes the smoke.

The objects of my invention I vaccomplish by the features ofconstruction and combination or arrangement of parts hereinafterdescribed, and speciically set forth in the claims, reference being madeto the accompanying drawings, in which- Figure 1 is a front elevation ofa range elnbodying my invention. Fig. 2 is a sectional view of the sametaken on the lineocx, Fig. 1. Fig. 3 is a sectional view taken on theline 'y y, Fig. 2. Fig. 4 is a vertical sectional view taken through thefire-box. Fig. 5 is a sectional view taken on the line e z, Fig. 1; andFig. 6 is a detail view of one ofthe dampers for the ascending reardues.

In order to enable those skilled'in the art to make anduse myinvention,l lwill now describe the same in detail, referring to thedrawings, Where- The numeral 1 indicates the framing of the range, and 2the 'top plate, having` removable rings 3, as usual, for pots, kettles,and the like.

The fire-box 4, having opening and closing doors 5 and 6, is locatedbetween the two opposite or side oven-chambers 7 and 8, which arefurnished, respectively, with adjustable shelves 9 and 10; and 12indicates the ashbox. v

In the base of the range,between the ovenchamber and beneath theash-box, is arranged a series of horizontalbaile-plates 13, providedwith alternating end openings or passages,

and in the front wall of the range, beneath the lower lbaffle-plate, isplaced a register or slide-door 14, of suitable construction to controlthe admission of the air to support combustion. The battle-plates aresupported at each side edge bya vertical partition-plate 15, suchpartitioirplates being so arranged, respectively, as to provide anascending flue 16 at the inner side of the oven-chamber 7 andanascending due 17 atthe innerside of the ovenchamber 8, said dues openingat their lower ends, respectively, into horizontal rectilinear chambers18 and 19, located between the base- Vplate ot' the range and the bottomwalls of the oven-chambers. Thevertical detlecting-plates 20 and 21 areplaced, respectively, in the chambers 18 and 19, their upper edgesjoining the bott-om walls of t-he oven-chambers and their lower edgesjoining the base-plate ofthe range. These deflecting-partitions arearranged diagonally and converge toward cach other from the rearvascending dues 22 and 23 toward the front wall of the range. Theascending dues 22 and 23 rise from the base of the range at theextreme'back thereof, one passing directly behind the rear wall of theoven-chamber 7 and the other behind the rear wall of the oven-chamber 8.

The dampers 24 and 25 are respectively pivoted in the rear ascendingtluesbelowthe top plate 2, and are furnished with cut-away or recessedrear edges to avoid accumulation of soot thereupon, and the dampers areprovided With cranks, to which are connected pull-rods 26 for swingingthe dainpers so as to open or close the upward passage of the productsof combustion through the rear ascending fines.

A diving side Hue 27 extends between the outer side wall of theoven-chamber 8 and the adjacent side wall of the range, and a similardiving side flue 28 extends between the outer side wall of theoven-chamber 7 and the adjacent side wall ot' the range, saiddiving-dues communicating respectively at their lower ends with therectilinear chambers located beneath the oven-chambers. The upper endsof the diving-fines communicate by lateral passages with the top of thecentral fire-box, such passages or tlues passing, respectively, over theovens and also over the side Water-legs 29 of a boiler 30, which at itsIOO rear is suspended or hangs down to form the back of the lire-box.

The tire-box is bounded at each side and at its rear by the inner wallsof the boiler, so that the lat-ter is eifectually heated, and betweenthe outer legs 2) and the inner side walls of the oven-chambers areprovided, rcspectively, the inner diving-fines 3l and 32, that permitthe downward passage of some products of combustion between thewaterlegs and oven-chambers.

In the rectilinear chambers in the base of the range are respectivelyarranged air-heating chambers and 311-, which are connected at one pointwith the external atmosphere by means of openings 35 and 36 in thefrontwall of the range and at another point with the lower portion otthe oven-chambers, as at 37 and 38, the object being to heat the airthat enters the oven-chambers. The air-heating chambers are cachcomposed of a series of communicating pipes or tubes, made so that theair must take a circuitous path, as indicated by the arrows 5. The topportions of the oven-chambers are provided with air-es cape orificescontrolled by slide or other dainpers 39, over which are iixed hoods 40,which project over the iiues 27 and 28, the object being to deiieet theescaping hot air and vapor down into said diving side iues 27 and 28, asindicated by arrows 6. The air to support combustion enters the registeror door 14, and in it: circuitous passage around the bathe-plates, asindicated by arrows 1, such air becomes highly heated by the heatradiated from the side plates l5, and in this condition such air risesbetween the gratebars to the lire, the object being to enable the rangeto consume the smoke. A flue 4:1,

ubeneath the boiler 30, conducts some heat thereunder to the chimney 42.The products of combustion rising' from the re pass laterally over thewater-legs 29, some pass ing down the diving-lines 3l and 32, asindicated by the arrows 3, and some crossing over the oven-chambers andpassing down the diving side tlues 27 and 2S, as indicated by arrows 2.The products of combustion pass from the diving side flues into therectilinear base-chambers 1S and 19, and bythe partition-plates aredeflected and thereby caused to pass over and heat the entire bottomwalls of the oven-chambers, from whence the products enter the ascendingrear iiues 22 and 23 and heat the oven-walls. The passage of theproducts of combustion, as explained, can be controlled by the dampers24. and 25, as will be obvious. The products of combustion in therectilinear base-eha1nbers heat the air in the hot-air chambers 33 and34, so that such air in the latter enters the oven in a hot conditionand passes out at the top, as indicated bythe arrows 6. While the ovensare being used the fire-box doors '5 6 are closed and the air to supportcombustion enters by the register or door le and orifices 43 and 44,formed, respectively, in the top of the ash-box and the framing of therange, the course et' the air entering the said orifices being indicatedby the arrows 4. It the dampers 2t and 25 are open and the damper 45 ofthe chimney 42 is closed, the products of combustion take the courseindicated by the arrows 2 to the chimney, while it' the dampers 2t and25 be closed and the chimney-damper 45 be `opened the products ot'combustion pass by flue Lil under the boiler direct to the chimney, asindicated by the arrows 5t. It it is desired to provide a slowlyburningfire, the register or door li is closed and the air to supportcombustion enters solely by the orifices 43 and at.
